Thanks for bringing this to our attention. When you say you're using TCO_Custom_Input, are you using the sample file which is in the Help section? Has that been modified at all or are you using as is? Can you please send us the inputs you're using? I tested the scenario you're describing using the sample file and have not been able to reproduce the issue. If you have a file to send, please email it to us at firstname.lastname@example.org. Thanks!
